New damselflies (Odonata: Zygoptera: Hemiphlebiidae,Dysagrionidae) from mid-Cretaceous Burmese amber

Zheng, D., Zhang, Q., Nel, A., Jarzembowski, E.A., Zhou, Z., Chang, S.-C. &; Wang, B., May 2016. New damselflies (Odonata: Zygoptera: Hemiphlebiidae, Dysagrionidae) from mid-Cretaceous Burmese amber. Alcheringa XX, xxx–xxx. ISSN 0311-5518

Two damselflies, Burmahemiphlebia zhangi gen. et sp. nov. and Palaeodysagrion cretacicus gen. et sp. nov., are described from the mid-Cretaceous Burmese amber. Burmahemiphlebia zhangi is the first record of Hemiphlebiidae from this amber, although the family was cosmopolitan during the Mesozoic. It can be readily distinguished from all other members of Hemiphlebiidae in having very short MP and CuA veins, and in its rectangular discoidal cell. The new fossils support the view that hemiphlebiid damselflies were one of the dominant groups of Zygoptera during the Mesozoic. Palaeodysagrion cretacicus is the first dysagrionid damselfly from Burmese amber and the second Mesozoic representative of this predominantly Paleogene group. It differs from other members of Dysagrionidae in having a unique elongate discoidal cell. These new finds increase the diversity of damselflies in mid-Cretaceous Burmese amber.

New fossil damsel–dragonfly clarifies the phylogenetic position of the small Jurassic family Juraheterophlebiidae (Odonata: Epiproctophora)

HUANG D. & NEL A., June 2017. New fossil damsel -dragonfly clarifies the phylogenetic position of the small Jurassic family Juraheterophlebiidae (Odonata: Epiproctophora). Alcheringa, 41, 536–542.

A nearly complete specimen of Juraheterophlebia cancellosa sp. nov., the third species of the family Juraheterophlebiidae, is described from the Middle–Late Jurassic of China and shows the exact structure of its forewing discoidal space. As a consequence, this family is restored, separated from Erichschmidtiidae, and its diagnosis amended. It is transferred from Heterophlebioptera to Stenophlebioptera, the first clade being now only known from the Early Jurassic. Erichschmidtiidae includes the sole species Erichschmidtia nigrimontana, and this family is now considered of uncertain systematic position.

Angel investing in an austerity economy – the take-up of government policies in Portugal

Business angels (BAs) are recognized as playing a significant role in stimulating entrepreneurial activity. With the decline in both bank lending and venture capital investment since the onset of the global economic crisis, government efforts to stimulate BA activity have become a more significant component in strategies to increase the level of entrepreneurial activity. This paper examines the responsiveness of angels to such initiatives in so-called austerity economies – countries that were hardest hit by the financial crisis of 2008 and subsequent global recession and, as a consequence, had to take extreme economic and fiscal measures to reduce their budget deficits. We examine this question in Portugal which experienced one of the deepest recessions in the European Union following the implementation of severe austerity measures. This study confirms that government intervention to support angel investing can have a positive impact. However, the different types of intervention have varied in take-up rates. Other countries can learn from the Portuguese experience in three ways: the types of interventions that have the highest and lowest levels of take-up, the link between the design and the take-up of incentives, and types of intervention that should be considered but have not been implemented in Portugal.     

Topoiesis: Procesos de espacialización en la literatura (crítica y metodología)

ABSTRACT

Space in literary texts has been widely studied but poorly systematized. There is no valid method of analysis that gives space a critical meaning. For instance, critics have eluded the fact that time and space cannot be considered separately. On the other hand, they have used concepts or methods from disciplines aside literature such as anthropology, biology, psychology, or geography that do not help clarify the meaning or signification of a literary text. We begin this article by giving a review of the main theoretical and critical positions regarding space in literature from the second half of the twentieth century. We do this in order to evaluate the main results those studies have attained. Later on, we propose a methodology that may clarify the significance of space in a literary text. The concept topoiesis (as far as we know, it has not been used in the humanities) represents for us a key word. It helps us to distinguish one main process where space can turn from a signification practice to the production of meaning in a literary text.     

Topoiesis de la recepción literaria

ABSTRACT

This article proposes a particular notion about “topoiesis,” focusing on the text reception point of view. Initially, it establishes a theoretical framework using useful concepts from hermeneutics and post-structuralism, to later discuss the real existence of a dialogue or a “fusion of horizons” in which a “sense of space” of a text would be blended in the meeting point between textuality and the reader. Finally, through this space we propose a categorization of the different types of “topoiesis” of literary reception, establishing correspondences with the concept of “enunciative instances” in the text space, detailed in another article.     

Topoiesis de las instancias enunciativas

ABSTRACT

The literary text is a communicative situation that involves a sender, a message, and a receiver. Literary theorists and critics have extensively studied the different instances of enunciation, making it clear that the author of a literary text is not the enunciator of it. This article intends to show that each one of them belongs to a distinctive level: those of the communicative situation and the enunciative situation. This article intends to show the space-time axis related to the situations mentioned above. This would allow the researcher to find the mechanisms of power that lie behind the authorization or discredit of a speech. By doing so, we intend to extend the analysis of the literary work, including the context of creation of the literary text. We would like to focus our attention on three aspects related to the enunciator: topoiesis of the communicative situation, topoiesis of the enunciative frame, and topoiesis of the writing individual.     

Towards New Paths for Regional and Territorial Development in Rural Areas

Abstract

The aim of this article is to shed some light on issues of territorial development and of rural development and to identify what links and opposes them. Indeed, everything pushes towards joining these two dimensions, which for a long time seemed disconnected. On the one hand, the policies targeting rural areas explicitly include the territorial dimension, while the distinction between rural and urban is getting blurred. In the meantime, decentralization, subsidiarity, the regionalization of agriculture, short circuits and local foods take place in parallel with the generalization of an urban model. Finally, we find that regional sciences are paying increasing attention to rural and agricultural dimensions, while studies concerning rural questions are starting to consider territorial issues. The first section of the article provides a critical presentation and attempts to define and distinguish the notions of development, territory and the rural. The second section addresses questions of regional and territorial development by presenting the main theories and public policies and concludes with a discussion about the possibilities of reconciling the theories and the policies. The third section follows the same structure, applied to the question of rural development, from analyses to grass-roots policies.     

Crafting identities in a multinational context: evidence from Catalonia

The nationalist messages that family and school transmit are very often concurrent, making it difficult to measure their independent impact on individuals. In order to separate out the leverage of these two agents of socialisation, this article focuses on a case study in which such concurrence cannot be taken for granted: Catalonia. The article exploits variation in parents' national identification, resulting from the presence of a population born in other regions of Spain outside Catalonia, to tease out the effect of both parents and Catalan school in crafting individuals' identification. The results, which draw on the analysis of a household survey, suggest that more years of schooling makes more likely that individuals develop a dual identity; however, parents' attachment to Catalonia is key in fostering an exclusive identification with Catalonia. Results also suggest that residence in neighbourhoods in which the proportion of natives and immigrants from other regions of Spain favours contact between children from different identity backgrounds is decisive in promoting a more Catalan‐oriented identification between second generations.
